Patei1tedJu1y27,1$15.

Application filed March 18, 1914. Serial No. 825,677.

To all whom it may concern.

Be it known that I, THOMAS J. Soon, a citizen of the i United States,residing at Marshfield, in the county of Coos, Stateof Oregon, haveinvented certain new and useful Improvements in Pipe Connections; and 1do hereby declare the following to be a full, clear,- and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in pipe connections in which asimple and efficient form of fastening means is provided wherebysections of pipe may be. securely connected together and positively heldagainst displacement.

A further object resides in the provision of a novel keeper element, therotation of which in one direction serves to retain the latch element inlocked position with the pipe sections, and rotation in the oppositedirection to release the latch element from locked engagement with thepipe sections and permit the disconnection thereof.

A still further object of the invention resides in the provision of astrong and durable fastening means of the above charactor, that may bemanufactured at comparatively low cost and quickly operated to place thesections of pipe in locked or unlocked relation.

With these and other objects of similar nature in view, the inventionconsists in the construction, combination and arrangement of parts setforth and falling within the scope of the appended claim.

In the accompanying drawing forming part of this specificationz- Figure1 is a view of two sections of stove pipe with the device appliedthereto and the parts shown in their locked position, Fig. 2

is a sectional view on the line 22 of Fig. 1, with the parts shown intheir released position, Fig. 3 is a view of a stove pipe and thimble,with the device applied thereto and the keper in its neutral position,and Fig. 4: is a perspective view of the keeper removed from the pipe.

Referring now to the drawing in which like characters of referencedesignate similar parts, the numerals 10 and 11 designate two sectionsof stove pipe of the usual construction, the adjacent ends of whichareeach provided with an opening 12, adapted to register when the sectionsare in their telescopic position.

Arranged longitudinally upon the pipe section 10, and secured thereto byrivets 13 or other suitable fastening means, is a latch member 14:, saidlatch being formed preferably of spring steel and provided at its freeend with a reduced portion 15. The latch 14 is further provided adjacentthe reduced portion 15, with a right angular projection or lug 16, saidprojection being adapted to pass within the openings 12 of the sections10 and 11 to lock said sections in interfitting relation.

Rotatably mounted on the pipe section 11 is a keeper disk 17, said diskbeing disposed in such position with respect to the latch 14, as toengage the reduced portion 15 thereof, and upon rotation in onedirection to lock the lug 16 in the openings 12, and rotation in theopposite direction to withdraw the lug 16 from the openings and permitof disconnection of the pipe sections. This disk is preferably stampedfrom a single blank of metal and has struck up therefrom a finger piece18, said piece forming the means whereby the disk may be rotated. Thedisk 17 is also formed with a notch 19 through which the reduced portionof the latch 14 is adapted to pass to its locked or unlocked position,and is further provided adjacent said notched portion with a cam surface20 and a cam edge 21, the former being engageable with the upper face ofthe reduced portion 15 toretain the lug 16 in the openings 12, and thelatter engageable with the under face of said reduced portion towithdraw the lug 16 from said openings.

The construction of the device shown in Fig. 3 of the drawings issimilar to that of Fig. 1, the elements being shown as connecting astove pipe and thimble instead of two sections of pipe and the keeper inits neutral position to permit the withdrawal of the lug 16 by meansother than the rotation of the keeper.

From the foregoing it will be apparent that I have provided a simple,strong, and inexpensive fastening means of the character described, andone in which novel means have been employed to retain the lug engageablewith the latch, whereby rotation of the keeper in one direction serves15 to retain the lug within the openings and rotation in the oppositedirection to withdraw said lug and permit of disconnection of said pipesections.

In testimony whereof, I aifix my signature, 2c

in the presence of tWo witnesses.
